Current situation:・Coal accounts for one fourth of global primary energy consumption and its consumption is
expected to increase. However, CO2 emission from coal is larger than other fossil fuels.
・As a result of continued R&D and effective O&M, Japan has achieved the highest
efficiency levels of coal-fired thermal power generation in the world. On the other hand,
there are many low-efficiency coal thermal power stations around the world.
・In Japan, coal has been re-evaluated as an important base-load power source in terms of
stability and cost effectiveness since the Great East Japan Earthquake and will be utilized
while reducing environmental load by effective use of high efficiency coal fired thermal
power plant.
Policy:・NEDO promotes R&D on high-efficiency clean coal technology (CCT) that contribute to
mitigate CO2 emission form coal fired thermal power plant including CO2 capture and
storage technology.
・NEDO aims to utilize these Japanese technologies to promote CCT overseas particularly in
developing countries, in order to stabilize energy supply and demand and contribute to the
establishment of a low-carbon society.
Priority activities:① Improvement of Coal-fired Power Generation Efficiency and reducing CO2 Emission
② Development of CO2 Capture Technology to realize Zero-emission Coal-fired Power Plant
③ Dissemination of High-efficiency Clean Coal Technology

Japan’s Power Generation by Source
Position and Policy Direction of Coal
(1)Position
Though coal has a problem – it emits a large amount of greenhouse gas – it is now
being re-evaluated as an important base-load power supply because it involves the
lowest geopolitical risk and has the lowest price per unit of heat energy among
fossil fuels. It is an energy source that we should use while reducing the
environmental load through the utilization of highly efficient coal thermal power
generation technology, etc.
(2)Policy Direction
In addition to promoting the replacement of aging thermal power plants and
introducing available leading-edge technology through the construction of new
facilities and the expansion of existing ones, GOJ further promotes the
development of technologies to drastically reduce greenhouse gas emissions per
unit of generated power(e.g., IGCC) by largely improving the power generation
efficiency. It is necessary to use coal while reducing the global environmental load
by promoting the introduction of such high-efficiency technologies not only in
Japan but also globally.
